The Prohibition of Anger
An excerpt from the book Sharḥ al-Arbaʿīn al-Nawawiyyah (Explanation of Nawawī's 40 Ḥadīth)
Undoubtedly, anger is from the Shayṭān.
On the authority of Abū Hurayrah (raḍī Allāhu ʿʿʿanhu) that a man said to the Prophet (ṣallallāhu ʿalayhi wa-sallam) "Advise me." He (ṣallallāhu ʿalayhi wa-sallam) said: "Don't become angry" So the man repeated (his request) several times (and each time) He (ṣallallāhu ʿalayhi wa-sallam) said: "Don't become angry." (AI-Bukhārī)
(Shaykh Ibn Daqīq al-ʿĪd explains): "The Author of Al-lfsaah1 said concerning what is understood (from this advice of the Prophet (ṣallallāhu ʿalayhi wa-sallam), that the Prophet (ṣallallāhu ʿalayhi wa-sallam) came to know about a great deal of anger on the part of this man so, (as a result of that) he (ṣallallāhu ʿalayhi wa-sallam) favored him with this advice.
The Prophet (ṣallallāhu ʿalayhi wa-sallam) has praised the one who controls himself at the time of anger. He (ṣallallāhu ʿalayhi wa-sallam) said: "The strong one is not the one who can fight, the strong one is the one who can control himself when he is angry."2
Allāh the Most High also praises (the one who controls himself when he's angry) saying:
وَالْكَاظِمِينَ الْغَيْظَ وَالْعَافِينَ عَنِ النَّاسِ
"... (Those who) repress anger and pardon men ... "3
It has also been related from the Prophet (ṣallallāhu ʿalayhi wa-sallam) that he said: "Whoever suppressed his anger while he has the ability to carry it out, Allāh will summon him on the Day of Resurrection before the leaders of the creation until he chooses whoever he wants from al-Hoor."4 5
It has also come in the ḥadīth: "Undoubtedly, anger is from the Shayṭān."6
As a result of this (anger which the Messenger of Allāh (ṣallallāhu ʿalayhi wa-sallam) said was from the Shayṭān) a person leaves his good condition, he will pursue and commit blameworthy actions and he will intend rancor, hatred and other than this from the shameful and forbidden acts. All of this is from anger, may Allāh give us refuge from it.
And it has come in the narration of Sulaymān ibn Sarud (raḍī Allāhu ʿʿʿanhu): "Seeking refuge in Allāh from the accursed Shayṭān will cause anger to go away."7
Surely the Shayṭān is the one who beautifies anger and makes it fair-seeming, and (he is the one who makes) everything that is not worthy of praise appear to be praiseworthy, so the Shayṭān deceives a person and causes him to become distant from the pleasure of Allāh thus seeking refuge in Allāh from him is from the strongest weapons against his plot."

 Reported by aI-Bukhārī in The Book of Adab, Chapter Warning against Anger, on the authority of Abū Hurayrah (raḍī Allāhu ʿʿʿanhu)
 Sūrah Āl-ʿImrān [3: 134]
 Reported by At Tirnidhee in the Book of al-Birr was-Silah wal-Adab, Chapter "Whoever Suppresses Anger", on the authority of Muʿādh Ibn Anas al-Junanī. And Al-Tirmidhī Said: This Ḥadīth is 'Ḥasan Gharīb'.
 Translator's Note] Al-Hoor l are very fair females created by Allāh as such not from the offspring of Ādam (ʿalayhi al-Salām), with intense black irises of their eyes and intense white sclera (for more info, refer to Hadī al-Irwah of Ibn Qayyim.)
 Reported by Aḥmad: On the authority of 'Atiyah as-Saʿdee (or 'Utbah as-Saʿdee, print wasn't clear enough [or translator to make out the name, wallāhul-musta'aan] The Prophet (ṣallallāhu ʿalayhi wa-sallam) said: "Undoubtedly, anger is from the Shayṭān and Shayṭān was created from fire and surely the thing that extinguishes the fire is water, so when one or you becomes angry let him make wuḍūʿ (falyatwada)" [Translator's note]: The narration of Muʿāwiyah (raḍī Allāhu ʿʿʿanhu) says: "Let him make Ghusl (Falyaghtasil)."
 Reported by al-Bukharī in The Book of Adab, Chapter Warning Against Anger, on the authority of Sulaymān ibn Sarud (raḍī Allāhu ʿʿʿanhu) who said, "Two men insulted one another in the presence of the Prophet (ṣallallāhu ʿalayhi wa-sallam) so one of them became angry, his face reddened, and his veins were popping out. The Prophet (ṣallallāhu ʿalayhi wa-sallam) looked at him and said "I know a word which will make your anger leave from you if you say it: 'a'udhoo billāhi min-ashayṭānir-rajeem.. '"
[Translator's note]: In this ḥadīth tile Prophet (ṣallallāhu ʿalayhi wa-sallam) has given us an antidote for anger which is al-Isti'aadhaah (seeking refuge in Allāh). However, this isn't the only remedy or antidote for anger as can be seen in footnote 6 above, which mentions making wuḍūʿ or ghusl as a remedy. Beyond these three antidotes there are more, such as duʿāʾʾʾ, as the Prophet (ṣallallāhu ʿalayhi wa-sallam) said, "I ask you (O Allāh, for the ability to speak a word of truth in times of ANGER as well as pleasure." (Sūrah al-Nisāʾ)
Another antidote is to shut up and be silent so as not to offend anyone as the Prophet (ṣallallāhu ʿalayhi wa-sallam) said: "If you become angry, then be silent" (Jami' aI-'Uloom wal-Hikam)
Another remedy is to sit down and/or lay down so as to lessen the chance of a person acting out on his anger as the Prophet (ṣallallāhu ʿalayhi wa-sallam) said: "If one of you becomes angry while he is standing then let him sit down, his anger will leave him, and if it doesn't then let him lie down." (Abū Dāwūd)
And the list goes on and the best guidance is the guidance of Muḥammad (ṣallallāhu ʿalayhi wa-sallam).
